BOGE AIR. THE AIR TO WORK.
The new license for energy saving: The BOGE
DUOTHERM external heat recovery system.
Embarking on heat recovery:
Retrofi tting or planning
from the start!
VERSATILE USE
Our external heat recovery system
is available in fi ve different versions
for oil injected screw compressors
from 7.5 and 110 kW. Apart from
the S series up to the S 150 model
the system can work equally effec-
tively with compressors made by
other manufacturers.
MAXIMUM EFFICIENCY
With the BOGE DUOTHERM
external heat recovery system
approx. 94 percent of the input
motor energy can be recovered
in the form of heat. Aside from
compressed air your compressor
can also produce hot water! –
a benefi t that rapidly pays off.
EASY INSTALLATION
The DUOTHERM module connects
into the oil circuit of your compres-
sor and can easily be fi tted by
a service technician. No external
energy is required for operation.
A further connection to a water
circuit is required and this should
be carried out by an installation en-
gineer – then you are ready to start
recovering energy and saving money.
COMPACT SOLUTION
Because of its compact design,
our external heat recovery system
does not require much space:
700 x 700 x 380 mm – that is all
you need to accomodate your new
energy saving device. An oil drip
pan (700 x 900 mm) is available as
an option.

this is how investing in a BOGE DUOTHERM
external heat recovery system rapidly
pays back.
EXAMPLE OF AN OIL INJECTED
S 150 SCREW COMPRESSOR
Rated power of the drive motor: 110 kW
Total power consumption: 123.4 kW
Motor effi ciency: 95 %
Use/year: 120 days
Compressor operation: 8 hours/day
Heating fuel price: 0.60 €/l
Calorifi c value of fuel: 10.1 kWh/l
Heating effi ciency: 70 %
Usable amount of heat: 72 %
usable energy x total power consumption
= heating recovery
Usable energy in oil circuit:
0.72 x 123.4 kW = 88,8 kW
Savings potential:
= Usable energy x operating hours x heating fuel price
calorifi c value of fuel x heating effi ciency
= 88.8 kW x 960 Oh x 0.60 €/l
10.1 kWh/l x 0.7
= 7234 € at 960 operating hours
Payback on assumed investment costs
of 5,000 Euros for DUOTHERM external
heat recovery system: < 1 year!
